The plot follows two young American women, Lindsay (Ashley C. Williams) and Jenny (Ashlynn Yennie), whose car suffers a blowout on a dark, isolated road in the German countryside. After being offered help by a mysterious driver, they are drugged and wake up in the basement of a man named Dr. Josef Heiter (Dieter Laser).
